Is it possible to limit the possibility of randomized label to show?

Let me explain what I am doing.
I am making a simple game that shows player two boxes at a time with a question, the player need to click one of the box to get to the next question. Clicking one of the box will lead player to the “correct” section while the other will lead player to the “wrong” section. There are 5 questions that player need to answer.

Now here is the problem and question.
Because of my concept of the game, I do not want to default which box is “correct” or “wrong”, therefore I have used the following code for EACH question to randomize the chance for the player to get “correct” or “wrong” label.


labelarray=[COLOR=#000000][[/COLOR][COLOR=#0000FF]"ques1_y"[/COLOR],[COLOR=#0000FF]"ques1_n"[/COLOR][COLOR=#000000]][/COLOR];  
randomidx = [COLOR=#993300]random[/COLOR][COLOR=#000000]([/COLOR]labelarray.[COLOR=#993300]length[/COLOR][COLOR=#000000])[/COLOR];  

ans_[COLOR=#000000]1[/COLOR].[COLOR=#993300]onRelease[/COLOR] = [COLOR=#993300]function[/COLOR][COLOR=#000000]([/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]     [COLOR=#993300]
gotoAndPlay[/COLOR][COLOR=#000000]([/COLOR]labelarray[COLOR=#000000][[/COLOR]randomidx[COLOR=#000000]][/COLOR][COLOR=#000000])[/COLOR]; 
[COLOR=#000000]}[/COLOR] 
ans_[COLOR=#000000]2[/COLOR].[COLOR=#993300]onRelease[/COLOR] = [COLOR=#993300]function[/COLOR][COLOR=#000000]([/COLOR][COLOR=#000000])[/COLOR] [COLOR=#000000]{[/COLOR]     [COLOR=#993300]
gotoAndPlay[/COLOR][COLOR=#000000]([/COLOR]labelarray[COLOR=#000000][[/COLOR]randomidx[COLOR=#000000]][/COLOR][COLOR=#000000])[/COLOR]; [COLOR=#000000]
}
[/COLOR]

All 5 questions and correct/wrong answers are all being done in one timeline with different layers, with labels to differentiate each section.

However, still because of the concept of my game, I actually want the player to get 3/5 “wrong”, is there any way I can limit the possibility of player getting correct or wrong while I have randomize the chance of it showing?
Or is it better for me to default the answer?

Thanks for reading and sorry for my poor explanation of the situation.
